1605 6544 d 7 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6544 d 7 h cejka /kernel/trunk/ Fixed printf return value.  
1601 6544 d 10 h jermar /kernel/trunk/ Support loading up to 8 userspace images on ia64.  
1600 6544 d 10 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6544 d 10 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6544 d 10 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6544 d 11 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
 
1594 6544 d 18 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6544 d 19 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6544 d 21 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6545 d 0 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6545 d 1 h jermar /kernel/trunk/generic/src/ In task_kill(), remove the task from the tasks_btree before proceeding.
Thus, when the kernel finds the task in the tasks_btree and locks it before
releasing tasks_lock, it is guaranteed that the task will not be destroyed
until the lock is held. If the kernel needs to unlock the task, do some operation
and lock it again, it should increase its refcount before doing so. In that case,
when releasing the lock, it must decrement the refcount and if it reaches
zero, it must call task_destroy().
 
1587 6545 d 2 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.
 
1586 6545 d 4 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6545 d 5 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6545 d 8 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6545 d 8 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6545 d 11 h jermar /kernel/trunk/generic/src/ Detach kmp thread after joining it.
Extend assertion in thread_destroy() to not panic when threads are destroyed in their Unded state.
 
1580 6545 d 11 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6545 d 21 h jermar /kernel/trunk/generic/ Framework for task_kill().
Some pieces (e.g. implementation of ktask_cleanup() kernel thread and
task_destroy() function) are missing.
Changed locking order for task lock, threads_lock and thread lock from
threads_lock, thread lock, task lock to task lock, threads_lock, thread lock.
